Barry was a naval hero of the Revolutionary War. He was born in Tacumshane, County
Wexford in 1745, and emigrated to Philadelphia in 1760. He joined the American forces at the outbreak of the war, and was the first
Catholic appointed to command a vessel by the Continental Congress. Barry's ship, Lexington,
was the first to capture a British vessel under the American flag. During much of the war, Barry commanded ships out of Boston Harbor, including the Delaware and the Alliance. After the war, President George Washington assigned Barry to help create the United States Navy.

Bostonians have been commemorating Barry's anniversary each
September on Boston Common dating back to 1919.
For a time in the 1940s the celebrants also journeyed into Boston Harbor.
Dan Horgan of the Irish World wrote:

"There is something sentimental, almost romantic about
this gesture, it's a scene almost anyone can picture in his mind.
Distinguished citizens of the Commonwealth getting up early in the morning going
out in a small boat, getting four or five miles out of Boston harbor, posing a
wreath in mid-air for a few minutes before casting it into the broad Atlantic
Ocean.”

At the Charitable Irish Society
annual dinner on March 17, 1949, Boston Mayor James Michael Curley
vowed to build a memorial to Barry in 60 days, saying Barry had been ignored for too long. The project got
underway, and the bronze memorial was actually unveiled seven months
later, on October 16, 1949.

Then
on April 5, 1975, some local college students stole the bronze plaque as a
prank. Contrition set in a few years later and the plaque was anonymously returned to the Massachusetts Ancient Order of Hibernians. The original was put in storage at the L Street Bathhouse in South Boston. Then on Saturday, September 12, 1981, the Barry memorial was transferred from the Boston Arts Commission to the National Parks Service for permanent display at the Charlestown Navy Yard, where it remains today.
